Please help improve stdlib by testing and reviewing pull requests!
The candidate for file system operations to be included in stdlib is being developed by @MarDiehl and @arjenmarkus in this repository. Please try it out and let us know how it works, if there are any issues, or if the API can be improved.
Fortran Package Manager#
Alpha release update: Last month saw the release of v0.3.0 for fpm which includes a number of new features and bug fixes.
Here is what is new in fpm:
#504: install.sh, README.md: Update version number, single source file extension
#501: Bump version for new release
#491: Catch execute_command_line errors and print useful messages
#500: Allow reading version number from file
#497: correct for equal sign in flag options to fix #495
#449: Response files with ar on Windows
#490: Minor fix to module parsing
#489: Redirect output when searching for archiver
#484: Add support for invoking simple plugins
#483: Allow fpm to change the working directory
Work in progress:
First beta release (WIP): First feature-complete release of the Fortran implementation.
#505 (WIP): quiet mode for #502
#498 (WIP): Draft - Compiler flags profiles
fpm is still in early development and we need as much help as we can get.
Here’s how you can help today:
Use it and let us know what you think! Read the fpm packaging guide to learn how to build your package with fpm, and the manifest reference to learn what are all the things that you can specify in the fpm.toml file.
Browse existing fpm packages on the fortran-lang website
Browse the open issues and see if you can help implement any fixes or features.
Adapt your Fortran package for fpm and submit it to the Registry.
Improve the documentation.
The short-term goal of fpm is to make development and installation of Fortran packages with dependencies easier. Its long term goal is to build a rich and decentralized ecosystem of Fortran packages and create a healthy environment in which new open source Fortran projects are created and published with ease.

Events#
We had our 13th Fortran Monthly call on June 15. You can watch the recording below:
Joint J3/WG5 (Fortran Standards Committees) meeting was held virtually from June 21-30 (Mondays and Wednesdays only). You can find all the papers that were discussed here. Highlights from the meeting:
Conditional expressions syntax for Fortran 202X (paper).
Protected components specifications and syntax for Fortran 202X (paper).
The generics feature planned for Fortran 202Y was discussed at depth (paper).
Jeff Hammond (NVidia Corporation) is the new J3 member as a voting alternate to Bryce Adelstein-Lelbach.
Target year for Fortran 202X is 2023, subject to change.
FortranCon 2021 will be held virtually from September 23-24, 2021. For more information, visit the FortranCon website.
Work has started for our Google Summer of Code program. You read about our students and their progress so far on Discourse: https://fortran-lang.discourse.group/c/gsoc-2021/11
As usual, subscribe to the mailing list and/or join the Discourse to stay tuned with the future meetings.
